4 Structure and Mechanism Technology of Lunar Lander
(2) The lunar rover separation mechanism was connected with the unlocking
device and the lifting device can work reliably under the high and low temperature environment on lunar surface to ensure the normal separation and release
of the lunar rover.
3. Configuration, Composition and Operation Mode off the Lunar Rover Separation Mechanism
For the Chang’E-3 lunar lander, the lunar rover was on the top of the lander. According
to the configuration characteristics of the lunar rover, special attention was paid to
the design of configuration of hold-down point, separation (release) mechanism,
support structure, lift and guidance mechanism for the lunar rover. There were main
components including the lunar rover bracket, separation mechanism for rover body,
hold-down and release mechanism for wheels, lift and guidance mechanism as shown
in Fig. 4.22.
The component function of separation mechanism for the Chang’E-3 lunar rover
was as follows:
(1) Lunar rover bracket: to provide support for the connection between the lunar
rover and lander, and installation interface for the separation mechanism for
rover body and the hold-down and release mechanism for wheels.
(2) Separation mechanism for rover body: to connect and release the lunar rover
body with the lunar rover bracket and withstand most of the loads during
launch and landing of the lunar rover as the major connection part of separation
mechanism for the lunar rover.
